9- Claims. (Cl. 15G-14) This invention relates to closures.; especially closuresI for windows. of. buildings, and.` particulariy closures. consisting largely of a sheet of pervious` material supported. by a skeleton` frame.

A principal; object. of this invention is the provision ci a closure of the.: type indicated which. will form a. complete.` closure. of an open window so that there will bean opportunity at no point for insects to pass.

A further object of the invention is the provision of a closure of the type indicated which is so constructed and applied that, it may be readily shifted inf position to allow one to protrude a portionl of the bod-ythrouglr theY window opening in order to more readily viewthe. outside,y and which may be readily entirelyremoved.

A further object of' the invention is the provisionl of a closure of the type. indicated which is so constructed that it ofers; a; obstruction to light, air, andxview..

A further object of the invention', is; the'provision of a closure of the type indicated which issov constructed that it is readily adaptable to window frames of standard' dimensions with slight variations therein, that is, variations not exceeding the generally allowable tolerance'.

'Other objects` and advantages `willappear as the particular physical embodiments selected to illustrate the. invention,` reference will be had to the accompanying drawings, and. the several Views thereon in which like characters of reference designate like parts throughout the several views, and' in which:

Figure 1' isa front elevational View' of a window, window frame, and a closure4 oi' my construction in place therein; Fig. 2 isa vertical sectional. View on the plane indicated by the; line II-II of Fig,... l, viewed in the direction of the arrows: at` the ends of the line; Fig'. 3. is a horizontal sectional view on the plane indicated by the line III--III of Fig. 1, viewed in the direction. of the arrows at the end's of theline; Fig. 4 is a fragmentary horizontal sectional view on the plane indicated by the line IV-IVof Fig.. l, viewed; in; the direction-r of the arrowsV at the ends: of the line; Fig.. 5 is a modi'ed form of constructionapplicable to the closure of Fig. 1'; Fig.. 6 is a. fragmentary perspective View of the left, hand edge of the closure as shown in Fig. l; Fig. 'Z is a` perspective view of a parting strip attachment forming; a. part of the construction of the device as shown by'Fig. l; Fi`g.` 8v illustrates the method of` applying the closureto avwindow; Fig. 91 illustrates. a mediiied form of closure; Fig. l01is a perspective. view illus;- tra-ting the. parti-ng `strip attachment means of the form as shown by Fig. 9; Fig. 1l illustrates another form of window closure; Fig.. 12` is a. horizontal cross-sectional ViewY on the line XII- XII of Fig. 11, viewed in the direction of the arrows at the ends of the line; Fig. 13A illus- 6d p trates another modified form of screen and window attachment; Fig; 14- illustrates the. parting strip attachment usable with the form ci closure as shown by Fig. 13'; Fig. l5 is a perspective view illustrating' another form of parting strip at- 65n Fig. 7,. is iirst, applied preferably tothe parting gl strip; This is done by inserting ordinary round head wood screws, as 7, 8 and 9 at. the proper positions therein tocooperate: with the slotted orices 10, 11 and- 12 in the; parting `strip attachment. The screws are inserted so. that a slight space exists between the innerside of the headv and the partingstrip just suiici'ent to receive material 13 of the thickness of the parting strip attachment. After the screws have been properly inserted, parting strip'` attachment P is Br positioned in line with the parting strip and over the screw and the heads of thev screws passed through thev larger portion of the slotted oriiceand then the parting strip attachment P is pushed downwardly so as to bring the shank ci the, screws within the narrow slots of the parting strip orifices. This secures the parting stri-p attachment P securelyV but removably to the parting strip.

The parting strip attachment P' is preferably 95 made of metal, and preferably ofa non-rusting metal` It is of the thickness as above described and of aI width no greater than that of .parting strip 4. The upper end of the parting strip attachrnenty P is strengthened by any appropriate construction such as by an enlargement or folding over as shown. at 132L in Fig. 7. This strengthened portion, or bumper provided as a stop' for the lower rail 14 of. the: upper sashv so that. when it is lowered while the closure is in place it Vwill be stopped vbefore coming in contact` with the fragile parts of the closure..

The parting strip attachment P is also provided? with. a wing l5 for a greater portion of` its-v length whi'ch acts as an abutment to prevent 110 outward movement of the somewhat fragile skeleton closure frame, and also serves as an insect shield for the space adjacent the edge of the closure.

At the foot of the parting strip attachment P a sideway slide preventer 16 is provided. This sideway slide preventer 16 is preferably formed integral with the parting strip attachment P by bending the metal to form substantially a closed channel with a slot 17 in one face thereof. This construction at the bottom of the parting strip attachment, I term a sideway slide preventer.

Near the top of the parting strip attachment P, I position an oscillatable combined sideway slide preventer and slide channel 18. This slide channel 18 is preferably formed of metal and is in substantially the form of a channel with a portion of one side 19 bent at a right angle to cause it to act as a sideway slide preventer. In the base 20 of the channel a through bore 21 is provided which cooperates with a bore 22 in the parting strip attachment P to receive a rivet which holds the member 18 in place upon the parting strip attachment P, but allows it to oscillate as rivet 23 is not headed tightly against the parts.

opening toward each other.

After the parting strip attachments have been properly positioned on the parting strips the skeleton frame carrying the previous material is then to be positioned in its proper place.

The skeleton frame carrying the previous material is preferably formed of metal and in substance consists of a rectangular frame 24 formed of channel material and securely joined at the corners or made substantially integral as by welding. Within this frame the pervious material 25 is secured; Both vertical edges of the frame are provided with members for cooperating with the sideway slide preventers of the parting strip attachments. These members, which I shall call iiange members, are virtually extensions of the vertical side channels and are designated 26. Each is vertually a channel having one leg 27 of the channel positioned within the sideway slide preventers, the face of the channel being received by the slot 17 of the bottom sideway slide -preventer and the slot 28 of the combined oscillating slide channel and the sideway slide preventer 18.

With a closure frame as described, placement in the window is afiected by oscillating the members 18 to the position as shown in Fig. 8, then the flanges 27 are slid into the members 18 .so that the frame is in the position designated, First Position in Fig. 8, then the closure is swung on the pivot formed by rivet 23 to the position designated Sec- -ond Position in Fig. 8, and then the closure is allowed to drop so that iiange 27 enters the bottom sideway slide preventer so as to assume the position designated Third Position in Fig. 8. When the closure has assumed the Third Position Athe parts are inA their final position and the window opening is completely closed against the en` trance of insects because the bottom of the frame rests upon the sill, the top of the frame is almost ,in rubbing engagement with the lower rail of the inner sash and the space between the sides of thev frame and the parting strips is securely closed by the wing members l5 and the bottom sideway slide preventer and the upper slide and sideway slide preventer.

When the closure is in place, not only is the window opening completely closed to the entrance of insects, but the closure itself is so secured that no ordinarly blow will displace it. At the same time, if one desires to secure a better View of the outside, it is necessary only to reverse the operations of placing the closure frame in the window to the point where it assumes the First Position as shown in Fig. 8, whereupon part of the body Amay be protruded from the window to procure a better view of the outside or to raise or lower an awning or perform a similar task. If it is desired to completely remove the closure, it is only nec-c"- sary to complete the revers-c operations by withdrawing the rectangular frame from the window by the oscillating members after it has reached the First Position.

Window frames as ordinarily constructed are generally of standard widths, that is, window frames come in sizes which vary by fixed amounts so that the distance between parting strips of various size windows is a standard. There is how-- ever some variation in manufacture, that is, there is some tolerance allowed, and furthermore window frames shrink and swell. It is necessary to provide for all of the above mentioned variations. This is very nicely done in applicants construction because the flange 27 has an allowable movement within both the upper oscillatable slide preventer and the lower sideway slide preventer, so that not only is variations in width of sizes amply provided for, but in addition, the frame is so held that even if the distance between parting strips is the very maximum, the rectangular frame will not separate from the parting strip attachment on either side because it will be prevented by the flange '27 comingv in contact with the right angle bend 29 of the bottom sideway slide preventer and the right angle bend 19 of the oscillatable slide.

Although applicant has illustrated his preferred form of mounting the top oscillatable slide 18 in Fig. 7, nevertheless, it may well be that an alternative forni such as is shown in Fig. 15 may be of better service. This alternative form of slide 18 is pivoted on a pin 30 which passes through two folded over portions 8l and 32 of member 15 and a folded over portion 33 of the sideway slide preventer 18.

In Fig. 5 applicant has illustrated a modied form of sideway slide preventer. This form of construction is applicable both to the bottom sideway slide preventer and the upper oscillatable sideway slide preventer. This construction includes two mutually cooperating corrugated parts. The vertical side piece 84 of the closure is eX- tended into a corrugated side piece 35 which ts between corrugated arms 36, forming a tortuous passage of a bottom sideway slide preventer 87 corresponding to 16. With this form of construction there may be considerable allowable variation between parting strips, and the rectangular frame will be securely held against sideway sliding, because when the screen is positioned in the First Position as shown in Fig. 8, when the corrugated sideway slide preventer is used, those corrugations will be inter-fitted which are suitteriall is: as is the rectangular frame All.

.at will without disturbing the closure.

nernevc In Fig.. :9 applicant has illustrated a modifiedr form of closure;` In this form the parting strip attachment is designated as a whole by P". It consists virtually of an angle having, in one leg,

orifices, as 38,` by which `it may be attached to a parting .st-rip. The .other .leg of the angleris :bent overboth at the top and at the bottom to form a channel 39 to receive the rectangular frame 40' carryingthe pervious material. In this form of construction screws are properly'attachedlto each of `the parting ystrips vand parting strip attachments P are placed `on the rectangular1 frame 40 and then the orifices `38 are engaged `with the screws of the parting frame. In this 4form of construction variations of width are provided for `by the channels 39 of the `parting strip attachment P. These allow relative sliding movement between'. the rectangular frame 40 and the parting strip attachments but the Window opening is completely closed beca/use yof the leg 41 of' the parting strip attachment bearing against the side strips of the rectangular frame 40.

A iurther'modied form :of `closure is :shown in Figs. 11 .and 12. This form is particularly appiicable to closures of fa. dimension from the top to the lbcttom such that it may be placed in a window Without `interference "by the upper sash. In this form, parting strip attachments P2 `are .attached to the parting strips and the rectangular frame for holding the pervious maof Fig. 1. This frame is put in position, however, by raising the frame to such a height that the bottom is even with the top of the parting strip attachments P2, then the frame is slid downwardly with the iianges 27 engaged within the parting strip attachments.

In Figs. 13 and 14 another form of closure is illustrated. This differs from that in Figs. 11 and 12Y in that the parting strip attachments differ. In this alternative form, the parting strip attachment designated as a whole by P3 is made in two parts, an upper part 42 and a lower part 43. The upper part 42 is pivoted, as by a screw `144, to the parting strip, and the lower part 43 is pivoted, as by a screw 45, to the parting strip. The rectangular frame carrying pervious material is made in thesame way as the frame shown in Fig. 1. It is inserted by moving the `parting strip iittings to the light line positions as shown in Fig. 14. When the upper parting strip tting-42 is turned into the light line position, as shown in Fig. 14, the rectangular frame may be slid into it and when it has reached the 1 `proper position the parting strip attachment may be made substantially vertical by pivoting upon the screw 44, and then the frame dropped into the lower portion 43 of the parting strip attachment P3. When the frame has been dropped to its lower position it serves to prevent pivoting of the members 42 and 43.

Applicants construction is particularly applicable for fabrication from metal but applicant wishes it to be understood that although metal `is preferred it is not at all necessary that metal be used, as the several parts may be equally well made of other material, such as wood.

Most of the forms shown are such that when in place the lower sash may be raised and lowered The upper sash may only be lowered to such position that its lower rail contacts with the top of the parting strip attachment.

In all of the forms shown the entire window space is unobstructed except for the slight obof 'a `windu' struction offered.` by thel .side pieces` of the rectangular frame and the bottom rail vof the recframe.. The top .rail of the rectangular frame offers `nn more obstruction than the lower nail lof the inner L Although I have particularly described partisular physical embodiments Jof my invention and explained the construction; principle, and mede of operation` thereof, nevertheless, 1 desire te have it understood that the forms selected.
